Description
Technical field
The present invention relates to diesel engine manufacturing process, particularly a kind of frock of diesel engine electrolysis deburring.
Background technology
Diesel engine, as the heart of the dynamic power machines such as passenger vehicle, requires to have the reliability of height.Wherein in the manufacture process of cylinder block inner chamber oil duct, the junction of each oil duct machined surface all can produce overlap or burr, need to manage to remove to burr, and burr is in inside cavity, be not easy to be found and to clear up, fail to clean out just in case remain in each hydraulic fluid port, affect to a great extent the behavior in service of diesel engine.
In prior art, generally by carrying out manual deburring with hairbrush, also adopt the means of electrochemical deburring, electrochemical deburring is the one application of method for electrochemical machining, to utilize metal parts in electrolyte, to produce the electrochemical principle of anodic solution, be that cylinder of diesel engine is anode, tool-electrode is negative electrode, when apply DC voltage between two-stage time, electrolyte flows through two-stage gap under certain pressure, the current density maximum producing at burr or the arris place of part, dissolves and rounding burr fast.
In electrochemical deburring technology, the frock of electrochemical deburring is important parts, and it makes anode part aim at accurately location with cathode tool, keeps certain electrolysis gap, makes that electrolyte is smooth and easy to be passed through.As shown in Figure 1, the frock of traditional electrochemical deburring comprises outer tube (electrode tube) and inner sleeve (referring to Fig. 3), outer tube is fixed on inner sleeve by sunk screw 15, outer tube is tool cathode, inner sleeve inside is electrolyte manhole appendix 14, the tube wall of outer tube is provided with some bullports 13, bullport 13 is communicated with electrolyte manhole appendix 14, in the time that the frock of electrochemical deburring is deep into cylinder block oil duct inner chamber, need to be fixed on fixture, circumferencial direction adopts 11 fixed positions, flat position, axially adopt end face 12 location to carry out command range, make bullport 13 aim at oil duct inner chamber machined surface junction (place of burr).
But, after above-mentioned frock is fixed on fixture, form by flat position bayonet socket is carried out circumferencial direction location, in the time that cylinder block inner chamber oil duct handing-over mouthful machining accuracy is slightly poor, cathode tool is with regard to the position of misalignment burr, electrolyte just can not be evenly distributed on around burr, and the effect of electrolysis is undesirable.In the time need to removing the burr in system's handing-over mouthful place, several hole, the relative position of bullport 13 needs high-precision requirement (referring to Fig. 1) simultaneously, if once skew, the electrolysis effectiveness of some of them burr is undesirable, and can not adjust.
The information that is disclosed in this background technology part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply that in any form this information structure has been the known prior art of persons skilled in the art.
Summary of the invention
The object of the present invention is to provide a kind of frock of diesel engine electrolysis deburring, can carry out electrochemical deburring to any position of the junction of cylinder block oil duct machined surface, frock processing is simple, assembles simple and easy.
For achieving the above object, the invention provides a kind of frock of diesel engine electrolysis deburring, comprising: electrode tube, its tube wall is provided with the bullport of at least one group of electrolyte, bullport be four above and evenly arrange along the circumferencial direction of electrode tube; Inner sleeve, it is located at the inside of electrode tube, and the tube chamber of inner sleeve is communicated with bullport.
Preferably, electrode tube is relative with inner sleeve fixing by sunk screw.
Preferably, bullport is four.
Preferably, one end of electrode tube is provided with the axial location end face for assembly tooling.
Compared with prior art, the present invention has following beneficial effect: by four above bullports are set, can effectively avoid causing because cylinder block oil duct inner chamber oilhole circumferencial direction machining accuracy is not high the impact of position skew, improve precision and the effect of electrochemical deburring, and, because bullport is along circumferentially evenly arranging, the mutual position accuracy demand of circumferencial direction that in frock, overall hole is need not strictly be controlled, improve the qualification rate of fabricating tools, also have, when this frock is assemblied on fixture, do not need circumferencial direction location, assemble simple and easy.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention is not subject to the restriction of detailed description of the invention.
Unless separately there is other clearly to represent, otherwise in whole description and claims, term " comprises " or its conversion was stated being understood to include as " comprising " or " including " etc. element or part, and do not get rid of other element or other part.
As shown in Figure 4, according to the frock of a kind of diesel engine electrolysis deburring of the specific embodiment of the invention, comprise electrode tube and inner sleeve (unmarked in figure), its tube wall is provided with the bullport 13a of at least one group of electrolyte, bullport 13a be four above and evenly arrange along the circumferencial direction of electrode tube, the present embodiment with 4 bullport 13a for describing, four orthogonal settings of bullport 13a.Inner sleeve is located at the inside of electrode tube, and particularly, electrode tube is relative with inner sleeve fixing by sunk screw 15.The tube chamber of inner sleeve is communicated with bullport 13a, the tube chamber part of inner sleeve is electrolyte manhole appendix 14, the electrolyte that enters electrolyte manhole appendix 14 can flow out through bullport 13a the outer wall of electrode tube, by four bullport 13a are evenly set on the tube wall of electrode tube, electrolyte can be evenly distributed in the outer wall of electrode tube fast, and then electrolyte is delivered to containing jagged whole circumferential position, can allow electrolyte be covered with fully around burr, and the electrolyte of whole circumference is more even, so need not consider the circumferential direction positional precision of cylinder block inner chamber oil duct processing interface, also can meet the equally distributed requirement of electrolyte energy, effectively improve the effect of electrochemical deburring.
As shown in Fig. 5 and 6, one end of electrode tube is provided with the axial location end face 12 for assembly tooling, but does not need location (referring to Fig. 6) at circumferencial direction, and this frock, in the time of clamping, is not considered the location of circumferencial direction yet, assembles simple and easy.
To sum up, by four above bullport 13a are set, can effectively avoid causing because cylinder block oil duct inner chamber oilhole circumferencial direction machining accuracy is not high the impact of position skew, improve precision and the effect of electrochemical deburring; Electrochemical deburring frock and fixture circumference do not need to locate with flat position bayonet socket, assemble simple and easy; Because bullport 13a is along circumferentially evenly arranging, the mutual position accuracy demand of circumferencial direction that in frock, overall hole is need not strictly be controlled, and improves the qualification rate of fabricating tools.
The aforementioned description to concrete exemplary of the present invention is in order to illustrate and the object of illustration.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.Exemplary embodiment is selected and the object described is to explain certain principles of the present invention and practical application thereof, thereby made those skilled in the art can realize and utilize various exemplary of the present invention and various selection and change.Scope of the present invention is intended to be limited by claims and equivalents thereof.
